Ask for an answer, what is going on with the engine failure light on

The engine fault light is not necessarily the engine failure, but more often some parameters exceed the standard value, such as exhaust emissions exceeding the standard, or for some reason the engine fires, etc.

Engine indicator refers to the indicator light used to show the working condition of the vehicle's engine. The indicator light is used to show the working condition of the vehicle engine, when the key door is opened, the vehicle self-test, the indicator light is lit and automatically extinguished, if it is always on, it means that the engine of the vehicle has a mechanical failure and needs to be repaired.

Whether it is always on or extinguished after ignition, if it is always on, the engine is faulty and needs to be repaired. The latter is an engine self-check.

An engine is a machine that can convert other forms of energy into mechanical energy, such as internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc. For example, the internal combustion engine usually converts chemical energy into mechanical energy.

With the development of automobile gasoline engines in the direction of high speed, high compression ratio, high power, low fuel consumption and low emissions, the traditional ignition device has not adapted to the requirements of use.

You need to go to the repair shop computer to read the data and fault codes to analyze the cause.

The engine fault light is used to show the working condition of the vehicle engine, when the key door is opened, the vehicle self-test, the indicator light is lit and automatically extinguished, if it is always on, it means that the engine of the vehicle has a mechanical failure and needs to be repaired.

1. The sensor is damaged, the contact is poor, or the signal is interrupted;

2. Poor engine maintenance;

3. The quality of fuel and oil is not good;

4. The combustion of mixed air and gas is insufficient;

5. Spark plug failure, ignition coil failure;

6. The fuel pump is faulty and the oil circuit is blocked;

7. The air conditioner filter is blocked.

The specific situation is analyzed as follows;

1. Sensor problems; The sensors mentioned here include water temperature, crankshaft position, air flow, intake air temperature, oxygen sensor, etc., when these sensors are damaged, poor contact or signal interruption, the ECU of the car can not accurately obtain the engine data, at this time it will cause the engine fault light to turn on.

2. Maintenance problems; Poor engine maintenance is the most common cause of engine failure to light up. We know that vehicles have a certain maintenance cycle, if the owner does not maintain on time, coupled with bad driving habits, then it will increase the burden of engine operation, and finally can only remind you through the fault light that you should care about your car.

3. Oil quality problems; The oil quality here includes fuel and engine oil, we know that the fuel filled by the car is generally marked, and the engine oil is also semi-synthetic and fully synthetic, the manufacturer will generally recommend the owner to use which grade of fuel, which type of engine oil, if the owner does not add as required, it will cause wear and tear of the engine in the long run, and the fault light is not to blame.

Poor combustion of the mixture; The failure of the spark plug, ignition coil, fuel pump, and oil circuit blockage of the engine will cause poor combustion of the engine mixture. Poor combustion of the mixture is caused by the problem of engine carbon deposition or knocking, and these will eventually be detected by the engine's oxygen sensor and reported to the ECU, which will naturally turn on the fault light to warn of the intake air intake problem; When the engine burns, it needs to take intake, and the air filter element is very important in this process, if the air filter element of the car is not clean, it will affect the air intake of the car if it is not cleaned regularly, and it will be very difficult to check the blockage of He Chan for a long time, and if it is serious, it will cause the engine failure light to turn on. pressurization issues; Intake booster lines and turbochargers can also cause engine failure lights to illuminate.

Among them, the most common is turbocharger damage, and at the same time, the vehicle will also have oil leakage, large oil consumption, and power loss.

308 Although there are many reasons for the lights, due to the age of squeezing engine power, the use of low-grade gasoline for the large compression ratio, I feel that the quality of gasoline is poor or the reason for the use of low grades is too large, it is recommended that large traffic gas stations fill up high-grade gasoline, and the car does not shake under the premise of running at high speed for a few minutes, and it should be restored within 2 days. No, check for other reasons. The rider question is mine.

<> "The car is a rather complex machine, a car has more than 10,000 parts around the body, and any part problem will have a certain impact on the car. After the engine fault light is on, how to solve it more perfectly?

What does the engine fault light mean During the driving of the car, or the moment the car is ignited, the car engine fault light on the dashboard lights up, usually a red or yellow light, once it is on, it will not disappear automatically in most cases, and it will disappear automatically in a few cases, which is the so-called engine fault light on. The engine fault signal is sent by the ECU (engine computer), and the ECU controls all the electronic equipment of the entire engine, such as electronic throttle, fuel injector, generator, fuel pump, etc., covering various systems such as air intake, exhaust, fuel, ignition, timing, etc. So if the engine failure light is on, what is the specific cause?

It can only be detected by computer. The reason why the engine failure light is on.

First of all, light the fault light, so as to tell the owner that the current engine system is faulty, and it should be checked and repaired in time. Secondly, this fault information will be stored and provided to the mechanic as a reference during maintenance, so as to solve the fault faster. In addition, in order to ensure that the engine can continue to run in the event of a failure, if the detected fault has little impact on the operation of the engine, the computer will directly ignore it, but in fact, the engine is not in good working condition at this time.

If a serious fault is detected, the computer will start the emergency program, and the engine can also work under the emergency program, but generally only to ensure that the engine can continue to run without stalling.

For this case, we need to make a preliminary judgment: de-energize the positive or negative pole of the car battery, disconnect it for a few seconds, and then install it. After that, start the car and see if the engine fault light will be lit when the instrument is still on, which means that there is no problem with the engine and there is no need to go to the repair shop to check.

Some high-end cars will lose a lot of data after the power is off, and it needs to be reset again, and the power off needs to be cautious] After doing it, you may encounter three situations: 1The light went out just after I got it down, but it came back a few days later.

2.After the power was cut off, the fault light still did not go out. This situation is that the engine is indeed faulty and needs to be tested by a repair shop.

Generally speaking, there are two situations when the engine fault light is on: (1): the yellow symbol light indicates that the engine is faulty, but the fault does not affect the normal operation of the engine, but it must be tested and repaired; （2）：

The red symbol light indicates that the engine has a serious fault, and it needs to be repaired immediately under normal circumstances, if it is in special road conditions, it can be used in an emergency, but it is necessary to pay attention to the working status of the engine at all times. If the water temperature is too high or the oil pressure warning light is on, if you obviously feel that the vehicle is faulty, you should immediately pull over and call the maintenance station to request rescue to avoid affecting the performance of the engine.

I believe that many car owners have encountered the phenomenon of engine failure lights. When we were listening to the ** while driving, the car engine lights suddenly turned on. What do we do to stop and check or continue driving, many car owners are confused about this.

What are the causes of car engine failure lights? Today, Bian Xiao will help you solve your confusion. The following article will tell you why the engine failure light is on.

The engine fault light is on.

Engine failure signals are emitted by the engine computer, which controls all the electronic equipment of the entire engine, such as electronic throttle valves, fuel injectors, generators, fuel pumps, etc. , covering intake, exhaust, fuel, ignition, timing and other systems. Then if the engine fault light is on, the engine fault light just means that something is abnormal in a certain system.

As for what the fault is, it needs to be interpreted with the help of a computer detector. Each brand of car has its own unique faults**.

Causes of engine failure lights.

1. The combustion state is not good.

Poor engine combustion condition is the main reason why the engine failure light is on. In the design of the car, in order to ensure that the engine is in good working condition and the normal working life of the engine, an oxygen sensor is designed and installed on the engine to monitor the combustion state of the engine. Once the engine burns badly, it will not only pollute the environment, but also lead to fuel waste and excessive wear and tear on the engine.

2.Poor fuel quality.

Many riders who find that the engine fault light is on have a feeling: the engine fault light suddenly turns on after adding a tank of fuel. Because the engine has requirements for the quality index of engine oil, especially as the engine has higher and higher requirements for various specifications, the quality index requirements for engine oil are also getting higher and higher.

3.The inside of the engine cylinder is not clean and there is carbon deposit.

After a period of use, some carbon deposits are bound to accumulate inside the engine. These carbon deposits themselves can lead to changes in engine design parameters, and at the same time, their properties are also unstable, and the accumulated heat can cause the engine to ignite disorderly, which can cause engine knocking. In this case, the engine failure light will illuminate.

The above is a detailed introduction to the causes of car engine failure lights. Hope it helps. When the engine failure light of our car is on, we must pay attention, because the engine, like the human heart, is the most core part.

When something goes wrong, it can seriously affect the performance of the car. When you feel that the car is out of order, be sure to stop on the side of the road in time and call the repair shop for support to avoid causing more damage to the engine.

What does it mean to call the engine fault light on behalf of the car during driving, or the moment the car hits and fires, the car engine failure light on the dashboard lights up, usually a red or yellow light, once it is on, it will not disappear automatically in most cases, and will disappear automatically in a few cases, which is the so-called engine fault light. Engine failure signals are sent by the ECU (Engine Computer).

Summary. Hello, dear, I found out the reason why the engine fault light is on: 1. The combustion state is not good, check whether the grease nozzle is blocked, and clean up the carbon deposit.

2. Engine knocking, regular maintenance of the car, go to the repair shop to clean the oil nozzle and oil circuit. 3. If the car is weak and the engine noise is too loud, it may be that the engine oil is not suitable, and the appropriate oil can be replaced. 4. There is obviously a sound of knocking on the cylinder, and the piston or cylinder liner should be replaced in time.

5. The fuel quality is not good, after the old fuel is released, replace it with better fuel. 6. The inside of the engine cylinder is not clean and there is deposited carbon, go to the repair shop to clean the cylinder.

There are three situations and treatment methods for the engine fault light: 1. After the engine fault light is on, the car cannot be started: this may be caused by the failure of the ignition parts or fuel pump, and the vehicle will definitely not be able to start, so it can only call a tow truck service and tow the vehicle to the maintenance point or 4S shop for maintenance.

2. Although the engine fault light is on, it can still be driven, and there is nothing abnormal in driving: at this time, either a sensor is faulty, or the vehicle has a false fault, and it is impossible to determine what causes the fault light to turn on, or go to the nearby maintenance point as soon as possible to check and repair. 3. The engine fault light is on, and the vehicle can be driven, but there will be shaking, acceleration weakness, etc

In this case, it is not recommended to drive the vehicle again, although the vehicle can still be driven, but continuing to drive will lead to increased failure, resulting in engine damage, and in severe cases, it will cause other failures. So don't continue driving, stop the car and call ** and wait for help.
